Deserved recognition and popularity enjoyed by amateur radio operators is quite simple and reliable circuit includes flip-flop on the two transistors and a pair of thyristors controlled them. It allows you to alternately switch the four incandescent lamps or garlands for the effect of “running lights”.
In the journal “modelist-Konstruktor” No. 10 for the year 1985 was published a description of the electronic disconnect switch (VMS) for the battery (AB) of the vehicle. The originality and simplicity of the scheme I liked. Of course, I used it on my car. And creatively. The result is a design which, unlike the prototype, allows you to successfully use e-VM even when the on-Board network contingencies of a short circuit. In addition, my design provides for the on indicator. But this added convenience.
The brake light is on every car. However, the day (and especially during Sunny weather), the light becomes less visible. My suggestion is to use for signaling braking and still the Parking lights (so much so that at dusk and at night, they automatically would go to work in the usual, regular mode). For this customization requires minimal intervention in the scheme of the onboard network of the car, and here is the result… In its high efficiency will make sure everyone who is brought to follow the car, stop signal, in which the day is highlighted by a “retrained diodes dimensions”.
Five years ago one of my friends purchased a garage with a cellar and worried about how and what to do to potatoes and other vegetables, planted for winter storage in the cellar, didn’t freeze? Remember, rescued his once-popular thermostat through a balanced bridge with the two thermistors. And recently another friend of mine, being in the same life situation, asked me to help him in the manufacture of such devices.
Amplifiers loved by many musical instrument — the electric guitar created a lot. Including the so-called effect of “distortion”, the essence of which is to limit the primary sine wave top and bottom, resulting in a large number of odd and even harmonics that give the sound of the solo guitar special melodiousness. About the original circuit solutions, allowing you to create in a home workshop good-quality amplifiers with the effect of “distortion”, repeatedly reported by its readers and “modelist-Konstruktor” (see, for example, No. 8’80, 2nd’88 magazine).
Applications I developed the thermostat is quite wide. It can be used, for example, to maintain the desired temperature in the vegetable stores, household incubators, in the hive. Combining simple designs with compact size and high efficiency design, this device differs from analogues of many well-known and even easy to use with built-in indicators on the LEDs.
